Horizon vs widelux

Greetings,
I have recently become intrigued with using a swing lens panoramic camera but am a little overwhelmed at the limited choices of cameras. I plan to use the camera as a diversion and to have a little bit of fun with the wide range of view. I will continue to use my xpan when I seek a high quality image.

So my question is this... Horizon 202, Horizon Perfekt or a used Widelux?
The Horizons are cheaper...do I get what I pay for and may regret it later? Is the upgrade from the 202 to the Perfekt worth paying twice as much? The Widelux are pricey and used... can I feel confident the camera will work well enough for the price?

There seems to be a love-hate relationship with these cameras and I would prefer to be a lover and not a hater.
